Construction & Design:
The kit’s pressure plate features ACT’s exclusive diaphragm spring design, which increases clamp load while minimizing deflection, resulting in longer clutch life and improved performance. Each diaphragm undergoes a rigorous four-stage heat treatment process to ensure durability and resistance to heat-related wear. The pressure plate cover is precision stamped to provide structural rigidity and consistent performance, while the cast pressure plate components are machined to absorb heat efficiently, preventing premature failure.
The sprung street disc is constructed with a robust center section and premium organic friction materials that offer excellent wear characteristics and heat tolerance. The steel backing plate enhances burst strength, ensuring the disc withstands the stresses of spirited driving and off-road conditions without compromising reliability.
